ABC News has confirmed that Giffords, who was injured in a shooting in Tuscon, Arizona on January 8, has received medical clearance to attend the launch of the space shuttle Endeavour, scheduled for Friday at 3:47 p.m. EST in Florida. Giffords’ husband Mark Kelly is commanding the last flight of the space shuttle.

Sources tell ABC News Giffords is set to fly out to the Kennedy Space Center from Houston on Wednesday.

Kelly has said for weeks that he wanted his wife to attend the launch, and that Giffords had indicated to him she wanted to go.

Giffords was injured during a shooting spree while meeting with constituents outside of a Safeway grocery. Six people were killed in the shooting and 12 others were injured. Giffords survived a gunshot wound to the left hemisphere of her brain.
